^ what the heck did that say

Good topic. The longer lever arm obviously produces more torque on the bearings. However, wheel bearing are designed to take not only severe vertical but severe side loads as well, especially in a sports car. Think about the side load when cornering really hard. This effect will obviously be larger with larger spacers. My gut instinct about the phyiscs, along with the fact that spacers are so widely available and used says that premature bearing wear will not be an issue. You do see nearly the same effect with aftermarket wheels with differing offsets as well. Don't think this has caused many folks premature bearing wear either.

Myself I do run spacers purely for looks reasons. In general they are kind of a "hack" but I am not ready to shell out the $ for wheels and tires quite yet.
